Sodium chloride (salt) is manufactured in solar saltpans.  Salt, an inexpensive and abundant commodity, plays a prominent role in the development of man’s activities.  The most abundant source of common salt is sea water.  It is manufactured by various methods, of which the solar evaporation of sea brine, backwater and sub-soil brine water is predominant.  The physico-chemical features and biological systems are essential for the proper functioning of saltpans.  This paper explains the physico-chemical parameters of brine at various stages i.e., (1) reservoir, (2) condenser and (3) crystall

Quantum cryptography is unconditional secure communication by using the phenomena of Heisenberg’s uncertainty principle, no-cloning theorem of photon of quantum mechanics. Further, conventional cryptography susceptible at present computer computation but processing speed grow more rapidly and quantum computer abruptly launch then classical cryptography not so useful, it is easily breakable with the help of quantum computers.

The purpose of this study is to evaluate the transfer of resistant markers through conjugation and transformation evaluation of transconjugate strains for stability of R – plasmid against different conditions like several passages and storage in different temperatures for different time period. Around 2423 clinical samples collected from hospitals and health centers in and around chennai, and 105 isolates confirmed for Salmonella enteric serovar typhi based on preliminary, biochemical and cultural characteristics.

‘Insight’ combines several ideas. It includes ‘classic’ areas, such as knowing who consumers are, what they do, where they are, what they buy, what they would like to buy, what media they are exposed to and what media they choose to view, listen to or read. It also includes more psychological areas – what consumers think and feel, what their objectives and strategies are, and how these influence the way they behave. The list of attributes to examine is long and it should remain in the hands of the researcher or data analyst which variables are retained in the model and which are excluded.

Dental panoramic radiographs or orthopantomographs, have received overwhelming attention from clinical researchers and dental practioners worldwide in the recent years. The credit for this interest is attributed to the potential use of orthopantomographs in the prediction of skeletal osteoporosis.

A -day sensitization workshop was organized on career choice in sciences and technology with case study in food science and technology for secondary school science students. The objectives of the workshop were to assess the knowledge of the students on science and technology, food science and technology as a career and entrepreneurship opportunities in food science and technology. Initially, a pre-test was conducted with a structured questionnaire to ask for their level of awareness on S&T, food science and technology and entrepreneurship.

The eyes are at particular risk for oxidative damage due to their high exposure to oxygen, a large amount of fatty acids in the retina and also high light exposure, environmental pollutants and ultraviolet rays. Oxidative stress to the largely retinal pigment epithelial cell layer (RPE) over time is reported to produce tissue dysfunction that contributes to the development of the pathogenesis of many diseases of the visual apparatus.

Nowadays, call centres are more and more numerous in Tunisia. Despite the high turnover in the incoming centre calls, many students work there for a definite period. For those who have opted for a whole career in it, they would often suffer from an acute state of stress. The following article deals with the call centres art, the work exhaustion syndrome “Burnout” and its determinants.

The study was carried out in degraded lands in Central Rift Valley area of Ethiopia in 2012. The main aims of the study were to assess the woody species composition, structure, regeneration, density and diversity in the area closures and in an open area; and to assess the socioeconomic importance of area closures to the local communities. Three area closures and one open area were considered. For vegetation survey, randomized sampling technique was used to locate the sample plots in each area. A total of 60 circular sample plots of each 314 m2area were used.
